"A groundless fear, boy," assured Ohms. "I have seen to it that the Time Door can never be closed. And now--good-bye, gentlemen. Or, to use the proper colloquialism--_so long, hombres!_" Ohms bowed from the waist, gave his ten-gallon hat a final tug, and took a single step forward. And did _not_ disappear. He stood, blinking. Then he swore, beat upon the unyielding wall of grayness with clenched fists, and fell back, panting, to his desk. "I've failed!" he moaned in a lost voice. "The C. Cydwick Ohms Time Door is a botch!" He buried his head in trembling hands. The reporters and photographers began to file out. Suddenly the professor raised his head. "_Listen!_" he warned. A slow rumbling, muted with distance, emanated from the dense grayness of the Time Door. Faint yips and whoopings were distinct above the rumble. The sounds grew steadily--to a thousand beating drums--to a rolling sea of thunder! Shrieking, the reporters and photographers scattered for the stairs. Ah, another knotty problem to be solved, mused Professor Cydwick Ohms, swinging, with some difficulty, onto one of three thousand Texas steers stampeding into the laboratory.
